Dear Aiden,
Since the Titan One mini 2.0 white is only compatible with SFX/SFX-L power supply,
The dimensions LxWxH is about 125mm x 100mm x 63.5mm.
And the MSI MAG A850GL ATX 3.0 850w is 140 x 150 x 86 mm.
So our Titan One mini 2.0 is not compatible.
Or do you like our Titan One mini 3.0? It includes the power supply.
Here is the link. It has a 10% discount now and free shipping.

The gigabyte rtx 4070 ti super gaming oc is 300mm long, it fits this case.
If you have any questions, feel free to contact us.
